Following are the main three things that alone or combined makes the 919 throttle jerky.
Too much cable slack, and assume any 919 never adjusted will have too much slack.
Super mush front springs that in low gear rolloffs or snapoffs from low speed, will make the fork dive.
Lousy mapping as can best be remedied by a PCIIIusb.
My experience was #1 was so obvious when I checked it, I did that first.
It helped, but did not at all cure it to an acceptable degree.
I found # 2 & 3 worked together to really make matters bad.
I sprung the bike for track day reasons primarily, and PC'd the bike as the mapping was horrid with stock cans or my Yoshi slipons.
Sprung, mapped and properly slacked has changed it from a on/off switch like bucking nightmare in slow crawly traffic that only clutch slippage could alleviate, to a rheostat like engine that I can walk down to below 1000 rpm in gear and never need to touch the clutch, even on a slight uphill grade with a passenger on.
